Founder's Story and the Team

In 1978, Our Transformer business Founder Mr. Lee started his career as transformer factory apprentice in Neijiang State Own Transformer Factory in Sichuan Province, the once one of the best transformer factories in Sichuan Province which has more than 100 million people, and then two years later he went to college for electrical engineering education. He backed to the factory after he finished the education and became a techinician in the factory, then to be the chief engineer, until the beginning of 21st century when most state owned factories were seeking to stop losing money by reforming the operation. 

Mr. Lee received Dr. Mohr’s guidance in 1996,  Dr. Mohr was then the head expert of five experts group invited by China Government to guide China dry type transformer design and manufacturing, to meet China’s increasing demand of high quality dry type transformers in airports, metro systems, hospitals, etc.

In 2006, Mr. Lee was invited to PC company again and received one more month training, then served as PC company’s guiding expert in China for many years, and directed the establishment and production of quite a few dry type transformer factories in China. So we are one of the first batch of factories in China which produce high quality dry type transformers and have accumulated a lot of experience.

In 2017, Mr. Lee founded ZHONGXIN GENERAL together with his long time friends in the industry. By Mr. Lee his own words, he has devoted all his life in transformer manufacturing and knows everything about it. Most of our workers and engineers have more than 10 years or 20 years experience in this industry, together with Mr. Lee’s guidance, it has formed a strong guaranty to Zhongxin General’s transformer’s reliable quality.

ZHONGXIN GENERAL 10kV Oil-immersed Transformer Characteristic:

Oxygen-free copper wire with lower resistivity is used for the ZHONGXIN TRANSFORMER 10kV distribution transformer. A series of additional surface treatment brings smoother surface without any burr and sharp corner, ensuring lower load loss and more electrical performance of transformer. 

*High-quality silicon steel sheets are adopted. For the improvement of performance level, lower unit loss silicon steel sheets are used to reduce the No-load Loss of transformers. 

*High-quality insulation parts are adopted, which never cracks or moves even under short-circuit current. 

*The chosen transformer oil has been strictly filtered, with less gas and impurity substance, which makes our transformers work more reliably. 

*High quality sealing materials is adopted to effectively prevent aging. 

*All raw materials that we adopt is under strict control of ISO90001 Quality System.

*Reasonable structure and high reliability of product operation; vacuum oil injection and stable insulating property; fully enclosed structure and maintain-free operation under normal conditions; beautiful appearance, easy installation, and significant energy-saving effect. 

Company Brief Introduction

ZHONGXIN GENERAL is a professional power transformer manufacturer located in Xinjin County, Chengdu City, Sichuan Province, China. Covering an area of 20 000 square meters with 200 employees, the factory is managed by transformer industry veteran who has more than 40 years experience. Mr. Lee, one of the founders of ZHONGXIN GENERAL, started as an apprentice in an state owned transformer factory in the late of 1970’s, later in the late of 1990’s he went to Germany to learn dry type transformer manufacturing technology, then helped to setup many transformer factories, and served as the German PC Company’s guiding expert in China. Worked in a State Owned factory as the chief engineer for ten years then another ten years in a Chengdu City Factory as chief engineer and factory establishment general advisor, then in 2017, at the age close to his 60s, Mr. Lee finally established ZHONGXIN GENERAL with his friends.
